The materials archived here document the data of CHES Canada and allow a replication of the analyses reported in 'CHES Canada', co-authored by Ruth Dassonneville and Jelle Koedam, that was published in the Canadian Journal of Political Science.

We deposit the following documents:

1. CHES_Canada_survey_2023.pdf: This document shows the questionnaire that was used for CHES Canada, with the question wording shown in English and in French.
2. ches-canada-analyses data note.do: This Stata do-file allows replicating all the analyses and figures reported in the CHES Canada note on new data paper. The dofile serves to replicate both the analyses reported in the main manuscript as well as the analyses that are reported in the Supplementary Materials.
3. The data folder includes the following .dta files:
- CHES_Canada 2023.dta is the main CHES Canada dataset, including the estimated party positions (i.e., the means of experts' assessments).
- CHES_Canada 2023_expert-level.dta is the expert level version of the dataset (i.e., before aggregation).
In addition, the folder includes the following files that are necessary for replication of the analyses reported in the paper:
- 2021 Canadian Election Study v1.0.dta: The data from the 2021 Canadian Election Study, administered by C-Dem.
- ces-opinion.dta: An aggregate level dataset of mean positions of respondents in the 2021 CES.
- Canada_v-party_gps.dta: A dataset with estimates of the positions of Canadian parties, sourced from other projects.
- CHES_polarization.dta: An aggregate level comparative dataset with estimates of levels of polarization.

For replication, we recommend storing all datafilee in a folder named 'data' and to create a 'figures' folder in the same directory for saving the graphs that will be generated when running the do-file.
